An optimized protocol for assessing changes in mouse whole-brain activity using opto-fMRI

Functional magnetic resonance imaging (fMRI) in mouse brain, paired with spatially and temporally defined manipulations, offers a powerful tool to causally explain the effect of specific neuronal activity on brain network dynamics. Here, we present an opti ...

Brainstem Correlates of a Cold Pressor Test Measured by Ultra-High Field fMRI

Dimitri Nestor Alice Van De Ville, Olivier Benoit Thomas Reynaud, Domenica Bueti, Fatma Megdiche

Introduction Modern imaging techniques such as blood oxygen level-dependent (BOLD) functional magnetic resonance imaging (fMRI) allow the non-invasive and indirect measurement of brain activity. Whether changes in signal intensity can be detected in small ...

Multi-slice passband bSSFP for human and rodent fMRI at ultra-high field

Rolf Gruetter, Ileana Ozana Jelescu, Rodrigo Araujo Fraga Da Silva, Olivier Benoit Thomas Reynaud

Balanced steady-state free precession (bSSFP) can be used as an alternative to gradient-echo (GE) EPI for BOLD functional MRI when image distortions and signal drop-outs are severe such as at ultra-high field. However, 3D-bSSFP acquisitions have distinct d ...

Fast model-based T-2 mapping using SAR-reduced simultaneous multislice excitation

Jean-Philippe Thiran, Tobias Kober, Tom Hilbert, José Pedro Rebelo Ferreira Marques

Purpose To obtain whole-brain high-resolution T-2 maps in 2 minutes by combining simultaneous multislice excitation and low-power PINS (power independent of number of slices) refocusing pulses with undersampling and a model-based reconstruction. Methods A ...

Ultra-High Field Birdcage Coils: a Comparison Study at 14.1T

Rolf Gruetter, Hongxia Lei, Tian Cheng, Arnaud Comment

An essential feature of magnetic resonance (MR) probes for magnetic resonance imaging and spectroscopy is the ability to generate uniform B-1(+) excitation in a volume of interest. When the magnetic field strength is increased, leading to an increase in re ...

A 7 tesla FMRI study of amygdala responses to fearful faces

Wietske Van der Zwaag, Nouchine Hadjikhani, Nicole Regula Zürcher Wimmer

The amygdalae are involved in the perception of emotions such as happiness, anger and fear. Because of their proximity to the sinuses, the image signal intensity in T2* weighted fMRI data is often affected by signal loss due to through-slice dephasing, esp ...

High Time-Resolved Cardiac Functional Imaging Using Temporal Regularization for Small Animal on a Clinical 3T Scanner

Dimitri Nestor Alice Van De Ville, Jean-Noël Hyacinthe

Accurate assessment of mice cardiac function with magnetic resonance imaging is essential for longitudinal studies and for drug development related to cardiovascular diseases. Whereas dedicated small animal MR scanners are not readily available, it would b ...

Spread spectrum magnetic resonance imaging

Jean-Philippe Thiran, Rolf Gruetter, Pierre Vandergheynst, Dimitri Nestor Alice Van De Ville, Yves Wiaux, José Pedro Rebelo Ferreira Marques, Gilles Puy

We propose a novel compressed sensing technique to accelerate the magnetic resonance imaging (MRI) acquisition process. The method, coined spread spectrum MRI or simply s2MRI, consists of pre-modulating the signal of interest by a linear chirp before rando ...

Fluorine-19 Magnetic Resonance Angiography of the Mouse

Yves Pilloud, Ruud van Heeswijk

Purpose: To implement and characterize a fluorine-19 (F-19) magnetic resonance imaging (MRI) technique and to test the hypothesis that the F-19 MRI signal in steady state after intravenous injection of a perfluoro-15-crown-5 ether (PCE) emulsion may be exp ...
